Kai is a very affable and affectionate child. Curious and active, we've taken to calling him "Farzzle". Lately, he has taken to zerbert-ing our legs, torsos, arms, shoulders, any available body part.
It's funny (and a little scary) how easily a word like "zerbert" immerses itself into our lexicon. "Thanks" Bill Cosby for that; and also for the "food" we call "Jell-o Pudding Pops".
